I once knew a feller, a travelling mate, not bad as 
fellers go,
He was happiest when he was miserable if ever that 
could be so,
He'd wake up every mornin' with the world upon his 
back,
And so for the want of a better name we called him 
Happy Jack.

If ever you travelled on outback tracks as most us 
sometimes do,
With anxious eyes on the petrol gauge in the hope it 
would see you through,
You're a 100 miles from nowhere and eighty still to go,
You'll hear his voice like the crack of doom "The 
petrol's gettin'low",

And when you're out on the Black Soul flats and you 
know what some rain can do,
You hope for the best as you head for the west, then 
you whisper a prayer or two,
And just when you're halfway over and starting to 
breath again,
You say with sigh and a mournful eye "I think we're in 
for rain."

And when on a long and lonely run with nothing in 
between,
The town you left is away in the past the next one a 
distant dream, 
He'll prick up his ears and listen and then in accents 
low,
"I don't like the noise she's makin' boss, the diff's 
about to go."

When you've bumped over corrugations, so deep you could 
bury a cow,
You say to yourself "It's pretty bad but the worst must 
be over now."
Then he'll look at you with a woeful look and furrows 
on his brow,
The last fifty miles on the road they say is "the worst 
in Australia now."

Oh I wonder where he is today, this travelling mate I 
had,
Where ever he is it's safe to say "That things are 
really bad.
If it's not the diff it's something else or the 
petrol's gettin' low."
It's pounds to peanuts and that's a bet, something's 
about to go.
